*Cohorts were assembled based on the current dose under consideration and retrospectively followed up to determine if they received the next dose. †Children 5–11 y of age: recommended interval between doses 1 and 2 was 8 wk so dose 2 due date was set at 9 wk (63 d). ‡Most children 12–15 y of age: recommended interval between doses 1 and 2 was 3 wk so the dose 2 due date was set at 4 wk (28 d). §For persons ≥16 y of age: recommended interval between doses 2 and 3 changed from November 2021 to January 2022 to 3 mo so the dose 3 due date was set at 91 d; 3 mo was also the most recently recommended interval between doses 3 and 4.
